Activity-based travel demand models (ABM) often use econometric models or heuristic rules to study activity participation and duration, focusing on independent variable effects. However, joint effects and the influence of emerging trends like telecommuting and online activities remain underexplored. This study investigates how individual attributes influence activity participation and duration, relationships between activity engagement and duration, and interdependencies among activities. Using data from Metro Vancouver, the study examines these dynamics across four groups: commuters, telecommuters, non-workers, and hybrid workers, based on 24-hour activity logs from the British Columbia Activity Time Use Survey. Findings from the Bayesian Belief Network (BBN) revealed significant direct and causal relationships between in-home and out-of-home activity participation and their durations. Furthermore, in-home activities influence each other, as do out-of-home activities. For example, out-of-home recreational activities and in-home recreational durations directly influence in-home social activity participation, while in-home personal business durations have an indirect effect for commuters. The number of children in a household directly influences participation in pick-up/drop-off activities. Similar activity relationships are observed among telecommuters, non-workers, and hybrid workers. The developed model will be implemented within a 24-hour ABM framework, currently under development at UBC Okanagan.
